The oil injection is mainly performed by opening the EVIO electro-valve
and by pouring, thanks to the pressure difference, the new oil (PAG or
POE) into the A/C system of the vehicle. The electro-valve opening is
temporized in Konfort 705R, 710R and 720R units, while in all the other
models is governed by the decrease of weight detected by the oil
injection load cell. At the end of injection, the equipment will check the
residual pressure into the system. This will ensure the possibility of
implementing the next phase.

2.2.6 UV Injection

During this phase, the equipment activates the following electrical
components:
Pressure sensor (1);
LP electro-valves (only for 760R, 760R Bus and 780R BiGas);
HP electro-valves (only for 760R, 760R Bus and 780R BiGas);
EVUV electro-valve;

The UV injection is similar to the oil one, thanks to the opening of the
EVUV electro-valve and of the pour, because of the pressure difference,
of the UV fluid into the A/C system of the vehicle. Once again, the
electro-valve opening is temporized in Konfort 710R and 720R units,
